Abstract
A method for manufacturing a deep hole comprises the following steps of 1, controlling a punch press to prepunch a hole in the set position of a workpiece; 2, milling out an annular section with the outer diameter larger than the hole diameter of a metal hole on the periphery of the metal hole, wherein the distance between the central axis of a miller and the central axis of the metal hole is smaller than one second of the radius of the metal hole, and enabling the miller to milling a stepped groove in the section of the metal hole; 3, continuously milling the hole in the stepped groove until the through distance of the whole hole is completed, wherein the miller rotates anticlockwise, and the error of the hole diameter is 0.1-0.5mm; 4, utilizing a broach to perform rotary broaching in the hole until the machining of the whole hole is completed, and utilizing a large file to perform surface smoothing on the inner side of the hole after the machining of the whole hole is completed. The deep hole manufactured by the method is high in precision and accurate in position, cutters are saved, and using efficiency of devices is improved.
Description
Technical field
The invention belongs to field of machining, particularly a kind of method of making deep hole.
Background technology
Using the broaching tool deep hole processing is processing mode commonly used in machining, but the common price comparison costliness of broaching tool, more accurate, if directly use broaching tool to draw deep hole, easily cause the damage of broaching tool, and can cause the machining accuracy of deep hole bad, therefore, if before using the broaching tool pulling eye, the deep hole of making except the size that meets the specification in advance is exactly technical issues that need to address.
Summary of the invention
The purpose of this invention is to provide a kind of method of making deep hole, the deep hole that this method is made, precision is high, and position is accurate, and has saved cutter, has improved the service efficiency of equipment.
The technical scheme adopted is:
A kind of method of making deep hole, comprise the following steps:
The first step, pretreatment parameter, control punch press and going out in advance hole at the workpiece desired location.
Second step, workpiece is moved to milling machine, in the metal aperture periphery, mill out the ring that external diameter is greater than the metal aperture aperture
The shape zone.
The milling cutter central shaft is less than 1/2nd of described metal aperture radius from the distance of metal aperture central shaft.
Make milling cutter mill out step trough in described metal porose area.
The 3rd step, continuation hole milling in step trough, until complete the elongated distance in whole hole.Milling cutter will be rotated counterclockwise, and aperture error is 0.1-0.5mm.
The 4th step, use broaching tool are rotated pulling eye in hole, until complete the processing in whole hole, after completing, can use large-scale file, to carrying out the smooth surface processing in hole.
Its advantage is:
The deep hole that method is made, precision is high, and position is accurate, and has saved cutter, has improved the service efficiency of equipment.
The specific embodiment
A kind of method of making deep hole, comprise the following steps:
The first step, pretreatment parameter, control punch press and going out in advance hole at the workpiece desired location.
Second step, workpiece is moved to milling machine, in the metal aperture periphery, mill out the ring that external diameter is greater than the metal aperture aperture
The shape zone.
The milling cutter central shaft is less than 1/2nd of described metal aperture radius from the distance of metal aperture central shaft.
Make milling cutter mill out step trough in described metal porose area.
The 3rd step, continuation hole milling in step trough, until complete the elongated distance in whole hole.Milling cutter will be rotated counterclockwise, and aperture error is 0.1-0.5mm.
The 4th step, use broaching tool are rotated pulling eye in hole, until complete the processing in whole hole, after completing, can use large-scale file, to carrying out the smooth surface processing in hole.
